As reported in this week&#8217;s <em>Proceedings  of the National Academy of Sciences Early Edition,<\/em> Stephan Thiberge of  Israel&#8217;s Weizmann Institute of Science and his colleagues have come up  with a way to use the scanning electron microscope, or SEM, on these  &#8220;wet&#8221; biological specimens. Samples to be examined by SEMs, which use  focused beams of electrons instead of light to scan the surface of  objects, traditionally must be held in a high-vacuum environment. Under  these conditions, a sample that holds water, such as a piece of tissue  or a cell, is explosively unstable, so it has to be dehydrated, changing  its normal appearance. To circumvent this problem, the researchers  found a way to protect the fluid-filled sample from the vacuum by using a  thin polymer membrane transparent to the electron beam. Using the &#8220;wet  SEM&#8221; technique, the researchers were able to see not only the exterior  of a cell, as in a traditional SEM, but its interior structures as well.  The researchers believe their method opens opportunities for medical  investigations, including tissue biopsies. <\/span><\/p>\n<h6><em>This news brief appeared in the Discoveries column of the <\/em>Boston Globe&#8217;s<em> Health\/Science section on 2\/24\/2004.<\/em><\/h6>\n","protected":false},"excerpt":{"rendered":"<p>Researchers have developed a powerful new method to peer inside cells and tissues.
